Clutter 1.6.0 2011-01-31
===============================================================================
• List of changes since Clutter 1.5.14
» Remove more private symbols from the X11 backend.
» Add CLUTTER_BIND_POSITION and CLUTTER_BIND_SIZE values to the
ClutterBindCoordinate enumeration; these are short-hand values
for binding both X and Y, or width and height, instead of
requiring two ClutterBindConstraint instances.
» Clean up in the X11 backend to reduce indirection.
» Small clean ups in the Win32 backend.
» Make Shift+Backspace behave like Backspace in ClutterText.
» Emit the ::new-frame signal even on the first frame of
ClutterTimeline, to allow setting up the initial state of an
animation.
» Fix an invalid memory access in ClutterAnimator.
» Flush the per-framebuffer journal when switching between
framebuffers.
» Generalize updating GLES2 uniforms.
» Add debug code for tracing clipping in Cogl.
» Improve the OSX event loop, re-using the same implementation
as GDK. Also, provide simple, core-like device support.
• Bugs fixed since Clutter 1.5.14
#2490 - OS X backend event loop improved
#2530 - animator: Animator uses key after freeing it
#2534 - Incorrect description of function 'clutter_actor_pop_internal'

Clutter 1.5.14 2011-01-24
===============================================================================
• List of changes since Clutter 1.5.12
» Allow getting the state modifiers from a ClutterClickAction.
» Fix ClutterDragAction to never leave the event delivery in
an unwanted state.
» Optimize state changes for texture and data states.
» Enable VBO support in Cogl for GLES2.
» Fix compilation on GLES1.1.
» Documentation fixes.
» ClutterGLXTexturePixmap has been deprecated; its parent class
ClutterX11TexturePixmap and the low level CoglTexturePixmapX11
API provide access to the same features.
» Be more resilient against timelines controlling the state of
other timelines during the clock tick.
» Provide defines for the windowing platforms, to allow portable
applications to include the correct header and select the
correct API depending on the target.
» Introduce a fast path for cogl_read_pixels() that uses the journal
to determine the position of a single pixel on the stage; this
fast path gracefully degrades to the usual render-based approach,
and should speed up picking considerably in the case of opaque
quads batched together.
» Support XInput axis data on valuator devices, and introduce XInput2
support for event translation and device hotplugging. The support
for XI and XI2 must still be explicitly enabled by the developer,
but it is now compiled in by default. It can be disabled at compile
time by passing --disable-xinput to the configure script.
» Clean up the unintentionally leaked internal symbols in the X11
and GLX backends.
» Allow defining the contents of the rows of a ListModel using
ClutterScript. This completes the ability to fully define a
ClutterListModel inside a UI definition file.
• Bugs fixed since Clutter 1.5.12
#1422, key input handler for eglnative
#1456, Hinting mishandling
#1721, XInput2 support
#2268, EGL backend dependent on X11 headers
#2400, Don't enable GL_POINT_SPRITE on GLES
#2497, should not throw away a program when just the texture
object has changed
#2512, shader: Don't notify properties when finalizing shaders
#2513, script-parser: Also honor properties of type GType
#2516, [PATCH] Fails to compile with --with-gles=1.1
#2518, introspection: Add missing (out) annotations for get_color()
#2520, Add API to get modifier type in ClutterClickAction
#2522, ClutterDragAction might indefinitely disable motion events
#2524, It's possible to receive a new-frame signal after stopping
a timeline
#2526, model: Fix some GObject-Introspection annotations
#2527, model: Change the column argument type to gint for
clutter_model_set_sort
#2528, model: Add support to define rows in ClutterScript

Clutter 1.5.8 2010-11-29
===============================================================================
• List of changes since Clutter 1.5.6
» Add a migration guide for code using Behaviours.
» Allow parsing rgb(), rgba(), hls() and hlsa() color definitions.
» Performance improvements for the ClutterX11TexturePixmap.
» For caching purposes, do not discard the Material or the compiled
shaders for Offscreen and Shader effects.
» Fix image height in 3D Cogl textures.
» Create a GLSL generation backend for materials, similar to the
ARBfp one; this backend is the default for GLES2.
» Use FBOs and cogl_read_pixels() to efficiently read back partial
texture data.
» Various fixes in paint volumes computation and caching.
» Use the internal scene graph walk API to remove the map/unmap
implementation requirement for composite actors and for
containers with internal children.
» Simplify the backend notification of layer changes.
» Queue clipped redraws for Expose events on X11.
» Plug leaks.
» Include a porting guide from Behaviours.

Clutter 1.5.6 2010-11-19
===============================================================================
• List of changes since Clutter 1.5.4
» Deprecate ClutterBehaviour and its sub-classes: the same functionality
is available using the animation framework.
» Add ClutterSnapConstraint, a constraint implementation that snaps
together the edges of two actors.
» Add ClutterPathConstraint::node-reached.
» Deprecate ClutterTimeoutPool and ClutterFrameSource: this API is
not used internally any more, and since it's not integrated with
the master clock it's of relative use.
» Add a named, global color palette.
» Add the ClutterTimeline:reverse property, for automatically
reversing the direction of a timeline after the emission of
the ::completed signal.
» Performance improvements in the clip stack.
» Do not use pointer grabs in ClutterClickAction.
» Improve the internally used Cogl API for primitives, paths and
buffers; this is the first step towards Cogl 2.0.
» Allow using the COGL_DEBUG environment variable to disable the
NPOTs support.
» Plug a nasty infinite loop in the XSETTINGS implementation.
» Internally rename CoglMaterial to CoglPipeline; this should make
it clearer that the API refers to the state of the GPU pipeline.
» Add support for clipped redraws on EGL using the NOK_swap_region
extension.
» Build fixes.
» Use the monotonic clock API if compiling against GLib ≥ 2.27.3.
» Update examples in the Cookbook.
» Add a Cookbook recipe for looping animations.
» Add more documentation on Constraints.
» Documentation fixes.

Clutter 1.5.2 (04/10/2010)
===============================================================================
• List of changes since Clutter 1.4.0
» Add API to ClutterActor to allow any actor to define its 3D paint
volume and its stage-relative 2D bounding box; the paint volume is
the 3D space occupied by an actor during the paint sequence. This
allows better sizing of the FBOs, and opens the door to scenegraph
culling and accurate clipped redraws. The mechanism is opt-in: actors
have to implement the get_paint_volume() virtual function. Callbacks
attached to the ::paint signal will also disable any culling and
clipped redraw in place internally.
» Plug a leak in ClutterActor by disposing all constraints.
» Rework the build system to be as non-recursive as possible; this should
speed up the build of Clutter, and makes the build layout easier to
understand and update.
» Remove the internal copy of JSON-GLib; the internal copy was falling
behind at a spectacular level, and it was actually making the build
rather complicated - also by adding an unwanted, but needed,
introspection data generation. The required JSON-GLib has also been
bumped to the new stable release, 0.12.0.
» Use g_object_install_properties() with GLib 2.26.
» Implement ClutterContainer::child-notify, which slipped through the
cracks of many development cycles without anyone noticing.
» Document and test clutter_actor_contains(), especially the corner
cases.
» Plug a leak in CoglTexture2DSliced.
» Plug a leak in ClutterAnimator's handling of timelines.
» Trap glXDestroyPixmap() in CoglTexturePixmapX11 to avoid BadDrawable
errors when the GLX pixmap is destroyed behind Cogl's back.

Clutter 1.3.6 (30/06/2010)
===============================================================================
• List of changes since Clutter 1.3.4
» Provide a fallback on GLX if the MESA_copy_sub_buffer extension is not
available, by using EXT_framebuffer_blit. Both mechanisms are also
throttled to avoid taking all resources when using them in a compositor
like Mutter.
» Use (and cache) fragment shaders instead of texture combiners inside
Cogl materials. Cogl will automatically fall back from GLSL to ARBfp
to fixed functions depending on the level of support of the underlying
GL implementation.
» Implement a new design for materials; this allows scaling up the
number of materials in a scene, and also makes copying materials
less expensive.
» Make Cogl materials responsible for depth testing, and add new
experimental API.
» Use the (modified) GLU tesselator to draw paths to a vertex buffer
object instead of using the stencil buffer, or the scanline rasterizer
on platforms without a stencil buffer.
» Add ClutterDeformEffect, a base class for effects that deform an
actor's geometry when painting it; ClutterPageTurnEffect is an
implementation of a "page curl" deformation using the DeformEffect
API.
» Always use scissoring when clipping, to reduce the amount of buffer
that has to be cleared.
» Allow ClutterShaderEffect sub-classes to use vertex shaders by setting
a constructor property; the default remains fragment shader.
» Remove the button of the press event from the DragAction::drag-begin
and DragAction::drag-end signals. This is an API break from 1.3.4.
» Do not promote clipped redraws to full redraws.
» Improve the consistency of the default state name in ClutterState,
both in the API and in the serialization format.
» Fix a rounding error with the Text layout size.
» Add utility functions for CoglMatrix and CoglColor.
» Avoid a re-allocation cycle warning when resizing the surface of
a CairoTexture actor from within the allocate() implementation.
» Do not add the GL libraries for the EGL X11 backend.
» Add more checks for size of data passed to the shader types GValue
functions.
» Add width and height to the BindConstraint.
» Parse actions, constraints and effects inside an actor definition
for ClutterScript.
» Merge the code of native and x11 backends for EGL into a single
backend; also allow creating GL context with the EGL backend.
» Use XSETTINGS to set up the backend configuration options, like
the font name, resolution, font options and double click options,
on X11; this also allows ClutterText actors created using the
default font name to be updated when the font name and options
change; similarly, this allows ClutterUnits to be updated when
the screen resolution changes.
» Implement the texture_from_pixmap extension support inside Cogl
itself, and unify ClutterX11TexturePixmap and ClutterGLXTexturePixmap.
» Documentation improvements in the API reference and in the cookbook.
» Use the -Bsymbolic-functions linker option on supported platforms
to avoid intra-library PLT jumps.
» Fix painting transparent stages on X11 using the :use-alpha property
of ClutterStage.
» Fix emission of scroll events on Windows.

Clutter 1.3.4 (07/06/2010)
===============================================================================
• List of changes since Clutter 1.3.2
» Add ClutterEffect, a ClutterActorMeta sub-class that affects the
way an actor paints itself.
» Clutter provides a base class for effects painting to an
offscreen buffer, and a base class for effects using the
GL programmable pipeline (through the GLSL shader language).
» Clutter also provides some simple, shader-based effects:
ClutterBlurEffect, ClutterColorizeEffect and
ClutterDesaturateEffect.
» Effects can be applied to any actor, and can also be stacked.
» Add ClutterClickAction, an action that provides "button-like"
semantics for any ClutterActor.
» ClutterDragAction now moves the actor to which it has been applied
by default, using a class handler for the ::drag-motion signal.
» Add the :pick-with-alpha property to ClutterTexture; this property
allows using the alpha channel of a texture when picking it.
» Regenerate the mipmaps on COGL textures when a texture is modified.
» Documentation and build fixes.

logic related to sizing and positioning.
» ClutterDragAction is an Action sub-class that implements
signals and properties for dragging actors.

» Fix rounding errors in the preferred height of the ClutterText
actor
» Remove redundant type checks in clutter_actor_get_paint_opacity()
» Add support for the GLX_INTEL_swap_event extension; when using this
extension on GLX the glXSwapBuffers() call becomes non-blocking and
Clutter will use an event to control the master clock.
» Improve consistency between ClutterBox and ClutterGroup.
» On X11, do not set the _NET_WM_PID and WM_TITLE properties on a
Stage X window if the window was not created by Clutter itself

Clutter 1.1.8 (08/02/2010)
===============================================================================
• List of changes since Clutter 1.1.6
» Added ClutterAnimator, a class that allows defining complex
implicit animations involving multiple actors and states; this
class is mostly meant to be used through the ClutterScript
definition format, but it provides a convenience C API for
easily building animations.
» New experimental COGL API to expose "hardware" buffers such as PBOs or
drm surfaces. This API can be used, for instance, to make texture
uploading faster.
» Fixed the issues with resizable stages getting a 1x1 window with
the X11 backends
» Expose input devices for every event; by default, X11 and Windows
backends expose the core devices only.
» Add the ClutterStage:key-focus property, for key focus tracking.
» Allow setting transformable value types in ClutterAnimation when
calling clutter_animation_bind() and clutter_animation_update().
» Delay the creation of the default Stage until clutter_stage_get_default()
is actually called; this reduces the work of clutter_init().
» Implement Ctrl+Delete and Ctrl+Backspace in ClutterText
» Improve the extendability of CoglTexture with internal backends.
» Add implicit texture atlasing; Cogl will try to put every texture
inside the same texture atlas by default, to avoid state changes
in the driver and (hopefully) improve performance.
» Fix notification of the cursor and selection changes in ClutterText;
this improves the usage of Clutter from A11Y toolkits.
» Do not wait for a frame if the system clock goes backwards.
» Fix the dirtying of the clip state; this unbreaks cogl_path_fill().
» Documentation and build fixes.

Clutter 1.1.6 (18/01/2010)
===============================================================================
• List of changes since Clutter 1.1.4
» Some fixes for the Win32 backend (bug #1905).
» Profiling support via the UProf library. Configure with
--enable-profile to get a report after each Clutter application is
run.
» Improved conformance tests with coverage reports via gcov.
» ClutterTexture no longer tries to read back texture data into
g_malloc'd memory on unrealize (bug #1842).
» The CGL_• defines from cogl-defines.h have been removed. These
should not have been used by any applications, but if they were
being used then please replace them either with the Cogl enums or
with the appropriate GL_• enum if you are using GL directly.
» Added a delete-event signal to the stage.
» Fix for using cogl_rectangle with different texture coordinates
for multiple layers (bug #1937).
» Fix for using stencil and depth buffers in FBOs on Intel drivers
in Mesa (bug #1873).
» Support for subtitles in ClutterMedia.
» ClutterGLX will now use an RGB visual by default. For
applications (and toolkit integration libraries) that want to
enable the ClutterStage:use-alpha property there is a new
function: clutter_x11_set_use_argb_visual().
» Fix ClutterText to allow using Pango markup and attributes in
the same actor (bug #1940).

Clutter 1.1.4 (03/01/2010)
===============================================================================
• List of changes since Clutter 1.1.2
» Update the ClutterScript parser to be more resilient, and support
constructor and ChildMeta properties. The parser also respects the
order of the properties in the UI definitions when applying them,
and will apply the properties of an Actor after building the scene
graph.
» Simplified the implementation of LayoutManager sub-classes, and added
support for animating a layout manager.
» Allow short-circuiting some layout operations by setting a specific
flag on ClutterActor.
» Improve caching of the preferred size of a ClutterActor.
» Allow declaring "internal children" for a ClutterContainer
implementation: the memory management of these actors will be deferred
entirely to the Container.
» Let the ClutterStage honour the :opacity property and the alpha component
of the stage color. This requires support in the Clutter backend used.
» Improve Windows and OSX backends.
» Simplify the feature detection code for OpenGL; this also reduced the
required OpenGL version to 1.2.
» Improve the matrix stack handling code. The matrices can be debugged by
using the COGL_DEBUG environment variable, assuming that Clutter was
compiled with the right configure-time switch.
» Improve COGL API for draw buffers, and for offscreen buffer support.
» Add support for text direction to ClutterActor.
» Documentation, introspection and build fixes.

Clutter 1.1.2 (23/10/2009)
===============================================================================
• List of changes since Clutter 1.0
» Add ClutterLayoutManager, an abstract proxy class for easily
writing layout management policies; also add ClutterLayoutMeta,
a class for storing layout properties.
» Add ClutterBox, a generic container actor that relies on a
ClutterLayoutManager instance to manage the layout of its
children.
» Add the following layout managers:
- ClutterFixedLayout - a layout manager implementing the
policy used by ClutterGroup
- ClutterBinLayout - a layout manager for packing actors
as layers inside the same area, with per-actor alignment
- ClutterFlowLayout - a layout manager arranging actors as
a reflowing grid
- ClutterBoxLayout - a layout manager arranging actors as
a single line
» Remove the requirement for the backend-specific implementation
of ClutterStage to be a ClutterActor: a Stage implementation must
only implement the ClutterStageWindow interface. This cleans up
the backend code.
» COGL source tree clean up and rationalization; COGL now
knows the platform, and not only the driver (GL or GLES) so
we can migrate part of the low-level backend code from Clutter
to COGL where it makes sense.
» Remove code duplication across whole COGL.
» The GLES 2.0 driver for COGL, and the EGLX backend for Clutter
have been fixed and confirmed working.
» Add "dump-pick-buffer" to CLUTTER_DEBUG: this debug options
dumps the contents of each pick() buffer into a PNG file, for
debugging purposes.
» Allow interpolating intervals of ClutterUnits for animating
unit-based properties.
» Increase strictness and correctness of the ClutterUnits
grammar parser.
» Add GValue transformation functions for ClutterPath to and
from a string.
» Fix word movement in ClutterText; implement GObject getter for
:use-markup; emit notification for :position; decouple the
:text property from the :use-markup property.
» Do not queue redraws or relayouts on actors currently being
destroyed.
» Support #rrggbb and #rgb notations for ClutterColor.
» Multiple bug fixes.
» Provide _NET_WM_PID on the X11 stage implementation.
» Documentation and Introspection annotation fixes.
» Add test units for the ClutterActor size requesition.
» Build fixes.
» Use AM_SILENT_RULES if Automake 1.11 is detected, and fall
back to Shave on older Automake versions.

Clutter 1.0.0 (28/07/2009)
===============================================================================
• List of changes since 0.9.8
» Allow per-stage disabling of motion event throttling; this should allow
platforms or applications that require all the motion events not for
drawing purposes to get them exactly like Clutter gets them from the
windowing system.
» Various documentation fixes.
» Add per-word key navigation inside ClutterText.
» Fix the RGB<->HLS conversion.
» Various fixes for the OSX backend.
» Various build-related fixes.

Clutter 0.9.8 (17/07/2009)
===============================================================================
• List of changes since 0.9.6
» Add more introspection annotations for language bindings.
» Fix a bug in clutter_animation_set_alpha(), which also broke the
clutter_actor_animate_with_alpha() function.
» Check if the stage requires a relayout before showing it; this fixes
a bug in the X11-based backends, especially under compositing window
managers, where a 640x480 window would flicker before the default
stage was shown for the first time.
» Performance fixes for Cogl.
» Sliced textures were broken by the COGL journalling.
» Use the redraw cycle when asynchronously loading textures from
files.
» Miscellaneous compilation fixes for the OS X and Windows backends.
» Allow querying from within the paint function of an Actor whether
the actor is currently being directly painted or by a Clone actor.
» In the GLX backend, when using the non-implicit sync-to-vblank inside
glXSwapBuffers(), call glFinish() to avoid potential tearing.

Clutter 0.9.6 (01/07/2009)
===============================================================================
• List of changes since 0.9.4:
» Allow the manipulation of the actor's transformation matrix, so that is
is possible to apply additional transformations in a way that is
compatible with the transformations already applied by the scene graph.
» Fix a race in the X11 backend that happened between resizing the stage
drawable and the call to glViewport().
» Merge the cogl-journal-batching branch; this branch implements batching
the geometry of the elements of the scene graph before sending it to
OpenGL, thus minimizing the number of state changes and improving the
overall performance of Clutter-based applications.
» Add more debugging states for Clutter and COGL, which allow the developer
to track the state of the journal; to check the VBO fallback paths; to
disable picking for reliable profiling; to disable software-side matrix
transformations in favour of the driver/GPU ones.
» Improve the ability to "break out" of COGL by using gl_begin/gl_end
semantics; applications that drop into raw GL are, though, ignoring all
the caching performed by COGL and might incur in performance issues.
» Fixed the :load-async and :load-data-async properties of Texture by
removing the unneeded G_PARAM_CONSTRUCT flag.
» Added an initial migration guide that shows the porting process from
older releases of Clutter to the 1.0 API; the first chapter deals with
the migration from ClutterEffect to the new implicit animations API.
» Fixed MT-safety for the master clock.

Clutter 0.9.4 (19/06/2009)
===============================================================================
• List of changes since 0.9.2:
» Set the layout height in ClutterText, so that wrapping and ellipsization
work correctly to fill all the allocated area.
» Remove all the units-based API, and migrate all the positional and
dimensional accessors to use floating point values when dealing with
pixels. All the properties dealing with pixels now that a floating
point value as well.
» Add the ability to track wether an actor is going to be painted or not,
using the "mapped" flag. This also allows Clutter to be more strict
in the handling of the scenegraph, ensuring correctness and avoiding
wasting resources on nodes that won't be painted.
» Add debugging facilities for COGL, similar to those of Clutter; through
them is also possible to have an on screen debugging mode that shows the
boundaries of each rectangle sent to the GPU.
» Rework "units" into real logical distance units that can be converted
between millimeters, typographic points and ems into pixels.
» Simplify the Animation class to avoid redundancy and the possibility
of it going out of sync with the Timeline and Alpha instances it uses.
» Move every operation into a single "master clock" source that advances
the timelines, dispatches events and redraws the stages in a predictable
sequence, thus avoiding unneeded redraws. The default is to follow the
sync-to-vblank cycle, if it is supported by the drivers.
» Cache the glyphs geometry into a vertex buffer object to avoid
resubmitting too much information to the GPU.
» Rework the behaviour of ClutterModel when a filter is applied.
» Allow submitting premultiplied texture data; this removes the need
for unpremultiplying data in CairoTexture.
» Add a simple API for submitting blending and texture combining modes
through a string description.
» Move Timelines to pure time-based objects.
» Lots of performance improvements.
» Removal of all the deprecated API.
» Removal of all the fixed point entry points.
» Lots of documentation fixes - the coverage is now 99% of the exported
1600 symbols for Clutter and 80%+ of the 300 exported symbols for COGL.
» Generate the GObject Introspection data for both Clutter and COGL
at build time.
» Build environment fixes.

Clutter 0.9.0 (30/01/2009)
===============================================================================
• List of changes between 0.8.6 and 0.9.0
» ClutterText is a new actor allowing text display, text editing
both in multi-line and single-line modes, and text selection using
the pointer devices and the keyboard. ClutterText supercedes both
ClutterLabel and ClutterEntry.
» ClutterClone is a new actor that allows cloning of other actors,
both simple and composite. ClutterClone supercedes ClutterCloneTexture.
» ClutterBindingPool is a new API that allows to easily add key bindings
to an actor.
» ClutterAnimation is a new API for implicit animations, similar to
the tweening API used in toolkits like jQuery, Tween and Flash. This
new API supercedes the ClutterEffect API.
» ClutterAlpha uses "animation modes" instead of raw function
pointers; it is still possible to pass alpha functions. The alpha
functions provided by Clutter have been removed from the public
API. It is possible to register global alpha functions and use
them though a logical id.
» The interval of the ClutterAlpha:alpha property has been changed
to a floating point value in the [ -1.0, 2.0 ] range; this allowed
the addition of "overshooting" easing modes.
» COGL now supports backface culling.
» The COGL-based Pango renderer is public API and it is accessible
to developers. It is also possible to access the PangoContext used
by Clutter in order to create PangoLayouts to render text.
» The ClutterFixed API has been moved to COGL.
» COGL does not depend on Clutter data types anymore.
» The ClutterMedia interface has been overhauled: implementations
now must only override the interface properties. The ranges of
some properties have been changed to normalized values.
» COGL now exposes only floating point entry points, and reserves
the eventual conversion to fixed point only when needed. The
fixed point type and macros are publicly available for developers
concerned about floating point operations.
» COGL has a new Vertex Attribues API that allows submitting an
extensible number of vertex attributes to OpenGL in a way that
does not require format conversions and allows fast re-use.
» COGL has a new Material API that decouples paths from fills; it
is possible to create an arbitrary path and fill it with a COGL
texture. The Material API also allows setting multiple texture
layers and defining the blend modes and colors.
» ClutterTexture has the ability to use a worker thread to asynchronously
load an image from a file, as long as the GLib threading support has
been enabled prior to calling clutter_init().
» Clutter now supports localization of the help output, and it
also supports globally setting the text direction for non left to
right locales.
» ClutterCairoTexture is a new actor that allows using Cairo
to draw on a ClutterTexture; since Cairo does not have an OpenGL
backend, the drawing is not hardware accelerated.
» Clutter has a unit testing suite, based on the GLib unit test
framework, which can be used to track regressions.
» A ClutterPath object has been added, and it is used by the
BehaviourPath. The Path object allows defining paths using a set
of coordinates and operations. A Path can be "painted" either using
COGL primitives or using Cairo primitives, allowing an easier way
to paint non-rectangular shaped actors.
» ClutterInterval is a simple object, used by ClutterAnimation, that
describes an interval between two values, and interpolates between
the initial and final values of the interval.

» Removed the ClutterBackend::get_display_size() and wrappers.
» Verify that the vertex shaders are successfully compiled when binding
them.
» Increase safety of the ClutterGLXTexturePixmap
• List of bugs fixed since 0.7.4
» #993 - Underline colors are sometimes wrong
Clutter 0.7.4 (25/06/2008), "Killer Koi"
===============================================================================
• List of changes between 0.7.2 and 0.7.4
» Fix the ClutterEntry actor after the clip API changes in COGL.
» Update the shaders generated for GLES 2.0.
» Add the ability to add search paths and look up files from
ClutterScript. This allows defining directories to store the
images to be loaded by a ClutterTexture.
» Fix the GLES 1.1 support.
» Warn if no usable pointer device are available on X11 backends.
» Improve the request for the best pixel format on win32.
» Fix a regression when sizing the ClutterStage on backends that
only support fixed size stages; now setting any size will result

Clutter 0.7.2 (23/06/2008), "Kedoke"
===============================================================================
• List of changes between 0.7.0 and 0.7.2
» ClutterTexture has a new :keep-aspect-ratio property; when it is set
to TRUE the texture will return a preferred width maintaining the
aspect ratio with the given height and a preferred height maintaining
the aspect ratio with the given width. This allows to set the width or
the height and have the texture automatically request the height or the
width respectively while maintaining the aspect ratio of the original
image.
» Added XINPUT support on the X11 backends; this provides an initial
support for multiple input devices. The API is X11-specific, and
provides support for querying at run-time support for XINPUT, for
getting a list of input devices and for getting the type of each
input device.
» The 'fruity' backend also features multiple device support.
• List of bugs fixed
» #816 - clutter_actor_request_coords() should take a const box.

» #984 - pango_clutter_render_layout() declared void
Clutter 0.7.0 (13/06/2008), "Booska"
===============================================================================
• List of changes between 0.6 and 0.7.0
» COGL, the underlying GL abstraction layer in Clutter, has been
completely rewritten from the ground up. Its no longer a conceptual
hack but a documented, fully featured library pretty much in its
own right. COGL abstracts over Open GL, Open GL ES 1.1 and now
OpenGL ES 2.0, providing a smart uniform API over these libraries
with various utility features such as texture tiling abstractions,
paths and primitive rendering, FBO, shaders, etc.
» Clutter now provides an experimental backend for the Apple(tm)
iPhone and iPod Touch families of products.
» The Windows platform is now natively supported instead of
relying on the SDL libraries. The win32 backend is still
experimental.
» The X11 based backends now feature support for Actors that wrap
external X drawables (i.e the texture-from-pixmap extension and
fallbacks)
» Clutter now seamlessly supports multiple stages on the backends
that allow this feature.
» The custom Pango renderer has been completely rewritten, now using
the more modern and maintained PangoCairo (instead of FT2), and avoids
nasty subclassing hacks, supports smooth fast scaling of text, has
many edge case issues fixed and it still is very efficient (using
a texture glyph cache). It is even a little bit faster.
» Better texture support, timeline improvements, ClutterLabel and
ClutterEntry improvements, and container child properties are among
the new features - too many to fit in the NEWS file.

the plane of a given ancestor and accessors to query whether an
actor is scaled or rotated
• List of bug fixed

==========================
• List of changes between 0.5.4 and 0.5.6
» Reverted a last minute change in the depth sorting function of
ClutterGroup.
» Added the clutter_actor_move_anchor_point() family of functions,
which will set the anchor point at the given coordinates while
adjusting the actor postion so that the relative position of the
actor toward its parent remains the same.
» Provide a fallback for finding the Clutter alpha functions inside
a UI definition for ClutterScript in case g_module_open() fails.
» Add initial Frame Buffer Objects support in ClutterTexture; using
FBOs, where supported by the hardware and drivers, it's possible to
create a ClutterTexture from any actor.

Clutter 0.5.4 (25/01/2008)
==========================
• List of changes between 0.5.2 and 0.5.4
» A clutter-x11-<major>.<minor> pkg-config file is installed along
with the clutter-<major>.<minor> and clutter-<backend>-<major>.<minor>
ones, for libraries and applications depending on the X11-based
backends (GLX and EGLX).
» Textures are correctly unrealized before changing and freeing the
main GL context.
» It is now possible to block the automatic call to clutter_main_quit()
when closing the stage window using the frame controls by connecting
an handler for the ::event signal on the Clutter stage and checking
for the CLUTTER_DELETE event type and returning TRUE. This allows
the usage of other main loops with GLib reactors (like Python's twisted)
with Clutter without triggering assertions by closing the stage window.

==========================
• List of changes between 0.5.0 and 0.5.2
» ClutterModelDefault has been renamed to ClutterListModel
» ClutterModel now has vector-based variants for append, prepend and
insert methods; these methods are useful for bindings
» Add units-based variant for clutter_actor_move_by()
• List of bugs fixed
» #694 - Handle GLhandleARB on OS X [Tommi Komulainen]
» #700 - Fix for clutter_effect_rotate() [Neil Roberts]
Clutter 0.5.0 (02/01/2008)
==========================
• List of changes between 0.4.2 and 0.5.0
» New event handling system: every actor with the CLUTTER_ACTOR_REACTIVE
flag set will receive events from the underlying backend; the event
propagation chain will be walked in two directions (from the actor to
the top-level container and back) with the ability to block it in
both phases.
» ClutterShader, an abstraction over the programmable OpenGL pipeline.
» ClutterScore, an object for controlling timelines; using a score
instance is possible to start multiple timelines at once, or start
a timeline after another has emitted the ::complete signal.
» ClutterScript, an object for parsing a scene from an external file or
a buffer; the scene is described using JSON (JavaScript Object Notation):
every object is defined using its class and properties, and container
objects can have their children defined as well. It is also possible
do describe top-level objects such as timelines and behaviours, and to
automatically connect signal handlers to signal names.
» ClutterTimelines duration can now be set in milliseconds using the
:duration property; the default framerate will be used to compute the
actual duration in frames. The default framerate will be set by the
backend, and can be overridden by the application.
» ClutterTimelines direction can now be set using the :direction
property; a timeline can be set to proceed forward or backward,
and the direction can also be change while the timeline is still
running.
» New, experimental OSX backend.
» Build environment for MS VisualStudio 2005.
» ClutterModel, a generic list-based model object that can be used to
implement actors following the Model-Viewer-Controller design pattern.
Clutter provides a default implementation of ClutterModel, called
ClutterModelDefault and using the GSequence data structure from GLib
to optimize insertion and look up.
» Add the ability to grab pointer and keyboard events: if an actor
is set to have a grab it'll be the only one receiving events until
it releases the grab.
» Add the ability for an actor to receive the key focus; an actor
with key focus will always receive the key events, even if it did
not acquire the keyboard grab.
» It is now possible to set the GL "fog" (also known as "depth cueing")
effect on the ClutterStage; if the fog is enabled, actors farther
away from the view point will fade into the stage background color.
» Each actor now has an "anchor point", a point defined in the actor's
coordinate space that will be used as the origin when scaling and
rotation transformations.
» Every pixel-based API has been doubled with a corresponding
ClutterUnits-based function (postfixed with a '-u'), for instance:
clutter_actor_set_position() - clutter_actor_set_positionu()
clutter_actor_set_size() - clutter_actor_set_sizeu()
clutter_actor_set_depth() - clutter_actor_set_depthu()
This allows sub-pixel precision and device independence.
» The ClutterLabel actor now tries very hard to provide a sane
default size, if no bounding box has been requested; this fixes
the :alignment property and allows the addition of the :justify
property.
» The SDL backend can now be compiled under win32 with MingW; this
backend is still marked as experimental.
» The OSX backend allows the compilation of Clutter under OS X; this
backend is experimental.

• List of changes between 0.3.1 and 0.4.0
» Many documentation additions and improvements.
» Display DPI now honours on backends its can be queried.
» Various big endian related fixes.
» ClutterBehaviourEllipse and ClutterBehaviourRotate API and
internals improvements.
» Add basic tslib support to eglnative backend (for touchscreen events)
» clutter_stage_get_actor_at_pos should now work on 16bpp displays.
» New ClutterEffect rotation calls.
» Allowing user resizing of the stage now optional.
(implemented by glx backend only currently)
» ClutterEntry UTF8 fixes and improved automatic initial sizing.
» Make ClutterActor GInitiallyUnowned.
» New ClutterBox API: each box has now a colour and a margin (distance
between the inner-border and the children); plus, each packed child
has a padding. Margins and paddings are expressed in ClutterUnits,
to ease the transition to the device independent units. You can use
clutter_box_set_default_padding() if you want the same padding for
each child.

========================
• List of changes between 0.3 and 0.3.1
» EGL. There are now 2 experimental EGL backends;
- 'eglx', the former EGL on X11 implementation (now renamed)
- 'eglnative', a new EGL 'native' backend which supporting non
X11 EGL implementations (i.e framebuffer).

Clutter 0.3 (29/06/2007)
========================
• List of changes between 0.2.3 and 0.3
» Clutter now supports both switchable windowing system and GL backends.
Window systems supported include GLX, EGL and SDL.
GL support includes OpenGL 1.2+ and OpenGL ES 1.1. This is
provided by a small basic abstraction layer 'cogl.h'. Cogl is not
yet documented - usage external to Clutter is not yet advised.
Backends may provide specific command line options.
Notes;
GLX
---
The GLX backend is built by default and is currently the most
developed, supported and featured windowing system backend. Only
OpenGL is supported via GLX.
SDL
---
Clutter has experimental support for using SDL. Open GL is supported as
is OpenGL ES via Dogles (very experimental).
EGL
---
Clutter has experimental support for using EGL. Only Open GL ES
is supported by EGL.
EGL support assumes an EGL implementation running atop X Windows.
Open GL ES.
-----------
Clutter now has experimental support for Open GL ES.
Current known issues;
+ Unrealising a ClutterTexture will not move pixel data from video
into system memory but simply destroy it.
+ BGRA, YUV Texture data not currently supported.
(Use the clutter_feature API to probe for above at runtime)
Open Source ES implementations this has been tested against
include `Vincent' and `dgles'. Support for commerical
implementations may require modifications to the configure.ac
script.

dgles: http://developer.hybrid.fi/dgles/index.html
» New ClutterEffect class provides a simplified (and thus less flexible)
API wrapping around behaviours, alphas and timelines.
» New Behaviours - bspline, ellipsis, rotation.
» New built in Alpha functions;
CLUTTER_ALPHA_SINE_INC
CLUTTER_ALPHA_SINE_DEC
CLUTTER_ALPHA_SINE_HALF
CLUTTER_ALPHA_SQUARE
CLUTTER_ALPHA_SMOOTHSTEP_INC
CLUTTER_ALPHA_SMOOTHSTEP_DEC
CLUTTER_ALPHA_EXP_INC
CLUTTER_ALPHA_EXP_DEC
» New Actors and interfaces
+ ClutterLayout, for writing extended layout support in actors
+ ClutterContainer, for generic container actors
+ ClutterBox, ClutterVBox and ClutterHBox layout actors.
+ ClutterEntry, text entry actor
» ClutterTexture now handles BGRA, YUV and premultiplied alpha data.
» All internal math now fixed point based.
» Clutter now has it own internal event queue.
» ClutterStage new features;
+ Title property for naming in window decorations.
+ Perspective setting - The stages perspective can now be modified.

» #215 - macro CLUTTER_MARK() not disabled for non-debug builds
Clutter 0.2 (18-01-2007)
========================
• List of changes between 0.2 and 0.1
» Bindings, GStreamer and GTK+ dependencies moved out of tree:
now Clutter strictly depends on Xlibs, OpenGL and GdkPixbuf only.
» Actors now have an initial floating reference; this means you
don't have to explicitely unref them: every memory an actor
allocates will be freed when the group containing the actor will
be destroyed.
» Add basic run-time detection of GL features.
+ Use GL_TEXTURE_RECTANGLE_ARB if available.
+ Attempt to set up sync to vblank (set CLUTTER_VBLANK=none to disable)
» Add API for behaviours. A ClutterBehaviour is an object which
drives a set of actors using one or more properties depending
on the value of an "alpha" function.
+ Provide simple behaviours: ClutterBehaviourOpacity,
ClutterBehaviourPath and ClutterBehaviourScale.
+ Provide simple alpha functions for ramps and sine waveforms.
» Add fixed point API for embedded platforms with no FPU.
» Add support for command line switches to Clutter, like debug
flags and abort on warnings; also allow application to hook up
into the initialisation sequence to add their own command line
switches.
» Add Pango GL renderer for Clutter, and use it to render text
inside the ClutterLabel actor; this decrease texture memory
usage.
» Redo Clutter Label widget, using the new Pango renderer.
» Clutter Textures do not store local pixbuf copy (of texture).
» Redo group and actor scale/sizing API and functionality.
» Add memory management API for ClutterColor, and string parsing.
• List of bug fixed
